Germs!

I always used to roll my eyes at people who talked about how many germs kids bring home from school, but not any more! Seriously!!! Jade has been back to school for 2 weeks, and I already have 3/4 kids with colds, and I can feel my throat getting scratchy too! Last winter it seemed like we had a never-ending cycle of colds going through our house, someone was always sick! I REALLY don't want a repeat this year, I have got to figure out how to cut down on the germs..........anyone have any ideas????
